Title: Laser emission mechanism for processing having mechanism for discriminating processing defect
Inventor: OKADA SHUNICHI
IPC: B23K26/064
Filed: 1995-10-18
Abstract: PROBLEM TO BE SOLVED: To improve processing efficiency by simultaneously deciding whether a processing condition is non-defective or defective by comparing the luminance detected by a luminance sensor with a criterion value. SOLUTION: The laser beam P sent from a laser beam machine body is made incident on a first condenser 9 and is condensed to the processing part A of a work W, by which the work is processed. At this time, a processing beam q is generated and is made into parallel beams by the condenser 9. These parallel beams are made incident on a second condenser 10. The component q1 progressing on a light axis line α is advanced in the as-it-is direction as q10 while being accompanied by some attenuation by a light diffuser 11 between the second condenser 10 and the first luminance sensor 12. The component is made incident only on the first luminance sensor 12. The component q2 except q1 is diffused by the light diffuser 11 and is made into a blurring beam q20 .  The beam is made partly incident as the beam of the luminance equal to the first luminance 12 and on the second luminance sensor 13 as well. Decision is made by making comparison with the reference value by using the ratio of q10 and q20 , by which the exact decision is made.

Filed: 1986-12-12
Abstract: PURPOSE:To reduce the fluctuation in the count value of a photoelectron pulse and to calculate the measurement of particles in real time, by a method wherein (M+1)-many pulse counter circuits corresponding to the number of additions of moving average processing are used in order to count the photoelectron pulse and successively operated to perform moving average processing. CONSTITUTION:(M+1)-many pulse counter circuits 21, 22... are used in the counting of a pulse and controlled by an (M+1)-bit shift register 51. By this method, a moving average can be processed in real time. Further, a comparator 55 comparing a preset value with a photoelectron pulse count value counted for a definite time is used to measure the time width of scattering light. Therefore, it can be confirmed whether scattering light during measurement is one from particles in real time. The comparator 55 and latch circuits 31, 32... are used to make it possible to detect the peak value of the scattering light in real time. From this peak value, the partical size or number density of the particles in a fluid can be measured in real time using a photon counting method.

Title: Range finder for passive type auto-focusing apparatus
Inventor: ISHIGURO MINORU
IPC: G01C3/06
Filed: 1991-10-15
Abstract: PURPOSE:To enable accurate measurement of a distance even for overlapping subjects by a method wherein the case when the absolute value of a primary difference is larger than a prescribed value is detected as a zero cross point on the occasion when secondary differences of output signals of three photo- sensors are calculated. CONSTITUTION:Output voltages corresponding to the luminance distribution of a subject are obtained by line sensors 10b, 20b and 30b. The secondary difference distribution of these voltages behaves at a zero level as a boundary. A zero cross point of this behavior becomes equal in the state of deviating from a prescribed reference part for the sensors 10b to 30b. The behavior is detected as the zero cross point on the occasion of calculating the secondary difference, only in the case when the absolute value of a primary difference is larger than a prescribed value. The amount of this deviation is detected in a coincidence circuit 70 by sliding a signal waveform of the zero cross behavior. A distance to the subject is calculated from the amount of this slide by a triangulation method. Even when an inflection point exists in a waveform of the primary difference due to the boundary of overlap of two subjects, according to this constitution, it is not detected as the zero cross point.
